ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 652,809, dated July 3, 1900.

Application filed February 5, 1900. Serial No. 4,006. (No model.)

To all whom, it may concern:

Be it known that I, SAMUEL ASBERY SMITH PORTER, a citizen of the United States, re-' siding at Pickens, in the county of Pickens and State of South Carolina, have invented certain new and usefullmprovements in R0- tary Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the will enable the engine to be adjusted an supported in various positions, making it possible to greatly increase the uses of the engine and to so change the position of the engine and its drive-shaft that power may be transmitted therefromin any desired direction at the will of the operator without requiring the employmentof numerous devices or gearing for changing the direction or angle of the transmission.

A further object is to provide a support provided with a suitable base and an adj us'table part and means for securing and prop erly holding the adjustable part in its adjusted positions on the base.

A further object is to generally improve and simplify the construction of devices of this character.

With such and other objects in view my invention is embodied in the novel parts, combinations, and arrangement thereof hereinafter described, and particularly set forth in the claims.

In the accompanying drawings 1 have illustrated one form of my improvement, but desire. it understood that I do not limit my invention to the particular construction which for the purpose of illustration 1 have therein delineated.

In the drawings, Figure 1 is a sectional elevation of an engine and supporting means embodying my invention. Fig. 2 is a sectional view on line 2 2 of Fig. 1. I

Referring to the drawings, A and A indicate the two side face-plates of a rotary engine, conveniently of the impact type. These face-plates are each provided centrally'with a suitable stuffing-box for the central engineshaft, which is indicated at B. Between the face-plates is a cylindrical ring or casing O, which is provided with a series of perforations, (indicated at 0,) through which and through registering holes in the side plates A and A pass bolts D for firmly securing the side plates and ring 0 together. Within the casing or cylinder thus formed is a partition E, conveniently midway between the plates A and A, and, like the latter, provided with a central hole for the shaft 13. The plate or partition E fits snugly and steam-tight Within the ring 0 and is secured thereto in any suit able manner, as by bolts. The partition thus ments, within each of which is fixedly mounted on the shaft B a piston or drive'wheel, the same being indicated at F and F; Each of the pistons is provided at its periphery with a series of buckets or pockets, the pockets f of one wheel being arranged oppositely to those f of the other wheel. The purpose of this opposite arrangement of the buckets or pockets is to enable the driving of the shaft in either direction.

G indicates a steam-inlet entering one of the cylinder-compartments adjacent the buckets of the cylinder therein and in proper relation to cause the fluid admitted thereby to properly impact on the buckets to cause the rotation of the piston and shaft in one direction. G indicates a similar inlet for motive fluid for the other piston and arranged to properly admit the fluid to cause by its impact the rotation of the second piston in the opposite direction. Each of the fluid-inlet pipes G and G is provided with asuitable valve, the same being indicated at g'and g. The pipes G and G may be and are shown as connected to a common supply H.

T indicates an exhaust for the motive fluid from the cylinder-compartments. This exhaust may be, as shown, common to both compartments and is so located relatively to the inlets for the two compartments as to divides the cylinder-casing into two compartpermit the motive fluid to have the proper driving effect on the pistons before reaching and passing out through the exhaust.

My improved supporting means for the engine comprises a base member K, adapted to be secured to any suitable support-such as a floor, framework, boiler, or the like--and this base may be fashioned for the particular support to which it is to be applied. The base is provided with a boss or part L, in which is adjustably mounted a post or standard Mf The post M is shown as being cylindrical and seated in a cylindrical bore or pocket in the boss L. Suitable means, such as a suflicient number of set-screws, (indicated at N,) are provided for holding the post M in the position to which it is adjusted. It will be observed that the post M can be adjusted both axially and circumferentially in the base.

0 0 indicate bearing-arms carried by the post M and adapted to extend one on either side of the cylinder-casing. Each post has at its end a bearing 0, in which the shaft B is journaled, suitable bearing boxes or covers 0 being provided and detachably secured to the bearin gs.

It will be observed that the cylinder-casing is supported on the shaft 13 and should be provided with some means to prevent rotation thereon during the operation of the engine. For this purpose I have shown a lock device carried by the post or one or both of its arms and adapted to engage a suitable part of the casin g and securely hold the same. The lock device is indicated atP and is shown as being a screw working in a screw-threaded socket P, the screw being adapted to engage a part of the cylinder-casing. The latter may, if desired, be provided with shoulders engaging the screw to insure a more rigid hold. From this description of the support and holding means for the casing it will be seen that the engine can be turned and secured with its shaft in any desired angle, and in case it is desirable to reverse or change the position of the base of the support the cylinder-casing can be rotated 011 the shaft and secured in proper position to effect a more advantageous or ready connection of theinlets and exhaust with the supply and exhaust pipes.

Q Q indicate driving or fly wheels secured to the shaft B, one on each side of the engine.

It is believed from the above description that the operation and use of the invention will be readily appreciated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isr 1. The combination with a base, of a post adjustably mounted on said base, a shaftjournaled in bearings carried by said post, a piston fixed on said shaft, acylinder-casing loose on said shaft and adapted to be turned thereon, and means forlocking said cylinder-casing in adjusted positions circumferentially of said shaft, substantially as described.

2. The combination of a rotary-engine casing, a shaft on which the same is rotatably mounted, a support for said shaft, means for securing said support in adjusted position, and means for holding said casing in circumferentially-adjusted positions on said shaft, substantially as described.

3. The combination of a rotary-engine casing, a shaft on which the casing is rotatably supported, a bearing-support for said shaft, and means for locking the casing in different positions eircumferentially relative to said shaft, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

SAMUEL ASBERY Slllllll PORTER.
